Red Tamper Evident Holographic Sticker
Red color holographic label
Red color holographic label. Tamper Proof.
Tamper evident red color holographic label.
1.The three-dimensional nature of the phase information of the object light because the hologram recording, reproduction, can be observed to match real objects as a realistic three-dimensional images. When the viewer changes position, you can see the part behind the object is blocked, you can see a realistic three-dimensional images.
2 Hologram can be tear up because the hologram record is the object beam and the reference beam interference fringes so severability. After it was split any debris can reproduce the complete subject's image, but resolution is affected to some extent.
3.Reproducing image scaling due to diffraction angle and wavelength, the hologram is irradiated with different wavelengths of laser reconstructed image enlarged or reduced occurs.
4 Hologram information capacity Daido a holographic plate repeated exposure records, and can reproduce the respective different images to intentionally.
D. Gabor in 1948 improved the electron microscope image quality are proposed, its significance lies in the complete record. Gabe has experiments to solve the basic problem of the invention of holography, wavefront recording and reproduction, but due to the lack of bright coherent light source (laser), the hologram imaging still poor quality. The Branch home they think has been the arrival of a new era of the show. Was not strong enough coherent radiation source, the development of holography into a dormant state. Facing huge obstacles only results its early researchers may not do not give up this optical display technology.
Holography bleak future until the early 1960s due to the work carried out by the radar laboratory of the University of Michigan in the United States that gives splendor to the laboratory engaged aperture antenna EN Leith, J. Upatnieks almost J aven et al. System into helium neon laser technology, Gabor epoch-making improvements, while successfully carrying out a record and reproduce the experimental three-dimensional diffuse objects the same period (1962), the former Soviet scientists of YN Denisyuk under G. Lipp2mann the standing wave natural color xerography won the Nobel Prize in Physics (1908) proposed the white light reflection hologram. applications from this research continues to develop, many scientists began their research in order to explore potential applications of hologram, such as hologram interferometry, holographic storage, holographic optical elements, hologram microscopy, display holography CGH, etc..
During this period, SA Benton rainbow holography invention opened display the holograms applications prelude (1980s industrialization molded holography is built on the basis of the Benton rainbow hologram). Their success Gabor holographic thought in won the Nobel Prize in Physics in 1971. The holographic technology applications continuous development since the 1960s. 1962 With the advent of the laser, Leith and upa Tenix (Leith and Upatnieks) in the Gabe holography based on the introduction of the concept of the carrier frequency invented the off-axis holography to overcome the image quality of the hologram The main problem of poor --- twin like, three-dimensional objects became holography research focus, but the imaging science was far more than economic development, production and observation of the cost of such a hologram is very expensive, holographic The surgery basically became high funding to maintain the unrealistic fantasies synonymous. 1969 Benton (Benton) invented the rainbow holography, setting off a new upsurge white display features holographic three-dimensional display. Rainbow hologram is a hologram white display plane reflection hologram and Danny Suker (Denisyuk), in addition to the hologram can be observed in the ordinary incandescent bright stereopair processing The process is simple, easy-to-copy advantages.
